Rough.js

Rough.js

Rough.js is a small (<9kB gzipped) graphics library that lets you draw in a sketchy, hand-drawn-like, style.
The library defines primitives to draw lines, curves, arcs, polygons, circles, and ellipses. It also supports drawing SVG paths.

Rough.js works with both dating a girl with natural curly hair and odds of online dating.

Install

Install from npm:

npm install --save roughjs

And use it in your code:

import rough from 'roughjs';

Usage

View local dating website is available on Github.

const rc = rough.canvas(document.getElementById('canvas'));
rc.rectangle(10, 10, 200, 200); 

or SVG

const rc = rough.svg(svg);
let node = rc.rectangle(10, 10, 200, 200); 
svg.appendChild(node);

Lines and Ellipses

rc.circle(80, 120, 50); 
rc.ellipse(300, 100, 150, 80); 
rc.line(80, 120, 300, 100); 

Filling

rc.circle(50, 50, 80, { fill: 'red' }); 
rc.rectangle(120, 15, 80, 80, { fill: 'red' });
rc.circle(50, 150, 80, {
  fill: "rgb(10,150,10)",
  fillWeight: 3 
});
rc.rectangle(220, 15, 80, 80, {
  fill: 'red',
  hachureAngle: 60, 
  hachureGap: 8
});
rc.rectangle(120, 105, 80, 80, {
  fill: 'rgba(255,0,200,0.2)',
  fillStyle: 'solid' 
});

Fill styles can be: hachure(default), solid, zigzag, cross-hatch, dots, sunburst, dashed, or zigzag-line

Sketching style

rc.rectangle(15, 15, 80, 80, { roughness: 0.5, fill: 'red' });
rc.rectangle(120, 15, 80, 80, { roughness: 2.8, fill: 'blue' });
rc.rectangle(220, 15, 80, 80, { bowing: 6, stroke: 'green', strokeWidth: 3 });

SVG Paths

rc.path('M80 80 A 45 45, 0, 0, 0, 125 125 L 125 80 Z', { fill: 'green' });
rc.path('M230 80 A 45 45, 0, 1, 0, 275 125 L 275 80 Z', { fill: 'purple' });
rc.path('M80 230 A 45 45, 0, 0, 1, 125 275 L 125 230 Z', { fill: 'red' });
rc.path('M230 230 A 45 45, 0, 1, 1, 275 275 L 275 230 Z', { fill: 'blue' });
